The approxyhttpprocessresponse function in modproxyhttp.c in the modproxy module in the Apache HTTP Server 2.0.63 and 2.2.8 does not limit the number of forwarded interim responses, which allows remote HTTP servers to cause a denial of service (memory consumption) via a large number of interim responses.
The sndseqosssynthmakeinfo function in sound/core/seq/oss/seqosssynth.c in the sound subsystem in the Linux kernel before 2.6.27-rc2 does not verify that the device number is within the range defined by maxsynthdev before returning certain data to the caller, which allows local users to obtain sensitive information.
